To all whom it may concern;

Belt known that I. \VALTER J OHN EEATTIE, a c tizen of the UnitedStates, residing at Cohoes, in the county of Albany and State of NewYork. have invented certain new and useful Improvements inFolding-Machines, of which the following is a specification.

My invention relates to machines for folding collar and cuff blanks andthe objects of my invention are to construct a machine the folder platesof which will be heated, and

- the folding and pressing of the goods will be overthe ed es of the diewhile the die is upon the bla upon the bed plate of the machine. 7 t

The invention also consists of novel conarts hereparticularly described.I I -aocomp mechanism illustrated in the accompanying drawings, in whichFigure 1 is a front proved folding machine; Fig. 2, an end elevation ofthe same; Fig. 3, a top. plan view; Fig. 4, a. plan view. of themechanism operatin the folder plates; Fig. 5, a vertical longitudinalsectional view of the top plate of the machine, showing the bed plateand folder plate in elevation; Fig. 6, a plan of the top plate of themachine showin the mechanism for operating the folder pltates; Fig. 7, afront elevation of the same; Fig. 8, an end view of the same; Figs. 9,10, and 11 are detail views showing the mechanism for j operating thefolder lates; Fig. 12, a top p an viewenlarged o the die and itsoperating mechanism and associated parts of the machine; Fig. 13, afront elevation; F 1g. 14, an end elevation of the same; Figs. 15 to 21are detail views of various parts of the die head; Fig. 22, a lan view,and Fig. 23, a

top surface Upon this t. lo the folding and pressingrpf re the collarand cufl blanks take place. folder-plates are located upon the top of betable 1 and are four in number and are ish these objects by means ofelevation of my imarranged 10 move inwardly, folding the edges of thegoods over .the die upon the heated bed plate of the machine. This topsurface plate or table of the machine doesnot have a continuous solidsurface, but has an open center in which the heated bed plate of themachine is located, the top surface of t which extends above the topsurface of the .table." The folding and pressing are done upon thisheated hed pl ate which is vertically movable, and the folder-platesfold the goods over the die upon this bed-plate as is described inUnited States Patent No. 666,766 issued January 29, 1901 to JohnMaitland and myself. The folder plates are operated by cranks 2, .3,attached to the revolving disks 3, outside of the center of the disks.There are four movable folder-plates which are operated by four cranks 2working in suitable hearings in the folder-plates and imparting themotion'of an arcof a'circle to them, moving them inward toward a die 10,when the die rests upon the goods 11 on the bed plate, and folds thegoods on al sides over the edges of the die as described in theformerpatent to \Iaitland and myself.

The revolving disks 3 are mounted upon shafts 4. Two of the revolvingdisks are located in front of the machine and two in the rear: Attachedto the lower ends of the shafts 4 in the front of the machine aresprocket gears 6, engaging with the sprocket chains 5. Thesprocketchains 5 are short, occupying simply. 'the sprocketgears.Attached to each endof the sprocket chains are extension rods 15. Oneextension rod 15 of each sprocket is attached at one end to the lever 7.and the other extension rod 15 is attached to the lever 11. Lever 7 isfol-- crumed at its lower end to the stationary part of the machine at8, and is movable sidewise by the person operating the machine. Lever 11is likewise fulcrumed at the lower part of the machine, but has nohandle for the person operating the machine. 12, 12 are two connectingllDKS connecting the respective'sprocket wheels 6 to arms 9 on the rearshafts 4 so that an operator moving the lever 7 by hand moves all fourdisks simultaneously. By moving the lever 7 to the right (Fig. 7) theextension rod 15 will niove't-he left hand sprocket wheel 5, which atthe same time, by means of the extension rod 15 attached to the lever 11will move the lever 11 to the left, which will atthe .ward.

same time, by means of the extension rod attached to, the right handsprocket wheel move that sprocket wheel. The two sprocket wheels movmgthe two front revolving disks will at the same time and by the samemovement revolve the revolving disks in the rear by means of theconnecting links 1:2, 12, thus all of the revolving disks will be movedby one operation simultaneously and the cranks 2 will likewise move thefolding plates in- 38 is a spring between the levers 7 and 11. Whenthose two levers are moved from-each other. as described the" sprinexpands. When the power is removed the force of the Spring 38 will bringthe levers back toward each other and they will resume their normalposition- The reverse motion also at the same time takes place in thesprockets and revolving disks,and the foldin plates are thus removedfrom over the goo s on the die 10. The lost motion between the sprocketsand the. levers is taken up by means of the nuts 16 meshing with thescrew threads on the ends of the extensionrods 15. This also allows forthe proper adjustment of the re volving disks and the cranks 2.

In order to press the blanks successfully it is necessary that thebedpla'te and the folder-plates be thoroughly heated when the pressingtakes place.

. 23 is the heated bed plate of the machine. The heated bed plate ishere shown as the top surfacekof a chamber 23 heated by steam or by anysuitable means. It is ver tically movable by means of the foot pedal 24,turning upon the fulcrum 25, and pushing upward t e rod 27 which bearsagainst the bottom of the movableheated box or ,foot edal 17 and theheated bed plate under the ie drops down. The folder-plates are removedfrom over the die 10 by the spring 38 drawing the levers 7 and 11 towardeachother as above described. The goods are ressed over the edges of thedie and reeased therefrom as hereinafter described. When the die-head israised it moves the heated bed plate 23 upward until it comes in contactwith the bottom of those portions of the folder-plates 50 which extendover the ed e of the heated bed-plate. [This raising 0 the heated bedplate 23 1s accomlished as follows: A connecting rod 33 1s ivoted to thehandle 22 of the die head 13 in hunt of a bracket 34 on the table 1 towhich said handle is hinged. Therefore, the

raising or the handle 22 pulls the connecting rod 33 upwardly. Theconnecting rod 33 is loosely'plvotedto a cross-arm or lever 31 by meansof a pin 14 on said arm started in a vertical slot in the lower end ofthe connecting rod33. The cross arm 31 is fair-named to the machine at30 near the other end so that when the handle 22 is raised the rod 33draws up the end of the cross arm 31 and turns the cross arm31 upon thefulcrum 30 and presses downward the other end, which in turn pressesdownward the rod 32 mnnecting that end of the cross arm 31 with the footpedal 17. This presses downward the foot pedal 17 which, turning uponits fulcrum 18 presses upward the rod 19, and

thus raises the heated bed plate to a position that its top surface willbe against the lower surface of that portion of the folding-plates 50which extends over the heated bed-plate when at rest. By reason of theloose connection between the rod 33 and the cross-arm 31 there is a.small amount of lost of the movable folder plates heated so that whenthey move over the goods they will be hot. In order to also keep the11111111 portion or body of the folderplates 50 hot, I providestationaryheating boxes, 46, 46 in contact sith the under side of saidfolder-plates when the folder-plates are at rest. boxes are on eachside. of the machine and may rest upon the top surface plate or table 1of the machine, as shown in Figs. 1, 2, 12 and 14 and. may be heated byany convenient means. The top surface of the boxes 46 are even with theto surface of the heated bed plate 23 when raised so that when thefolderplates 50 are at rest they will lie upon the top of theseiheatedboxes and thus become thoroughly heated and then when they are movedover the die they will be hot so 3% to make a successful fold. In thepresent instance, the boxes 46 are heated by steam conducted thcreto bypipes 41, as shown in Figs. 1, 5 and 26. The folder-plates do not moveback far enough to allow the entire plate to rest over the stationaryheated boxes 46 but the edges of the movable folder-plates remain overthe movable heated bed-plate.

Therefore, I'employ the means above de-' Those the bottom of the edgesof the movable folder-plates will not be perfectand the folder-plateswill not be sufficiently heated.

The collar and unit blanks to be pressed are of irregular shape, and thestyles, especially of the collars, are constantly changing. In thedrawings, I have-shown a die for folding a collar blank which is of thesame shape and size as the collar. 1 make my die 10 plate ot very thinspring steel, and prefer-' i nected the respective sections 36and 3Tv ofthe die. The central plate is rigidly attached to the plate "28; one ofthe side plates, in this case plate 2-1. is attached slidably to the barand the other plate 26, I adjust ably attaehthereto, so asto lengthenthe die 10 to suit the size of the collar. The plate 26 may be adjustedon the bar 28 by means of set-screws 3 20 IS alink arm shorter than thehandle 30.22 and pivoted on the machine within the hinge of the. handle22 as shown in Figs. 12

Y and 14.

:21 is a wedge or cant attached to the end' of link 20 and adapted to beinserted between the plates 21- and 25, 25 being rigidlv at tached tothe bar 28 and '24 being slidablyattached to said bar. The cam 21 isadapted to slide the plate 24. carrying the end section of the die 10lengthwise, the link 20 and hinged at a point inside of the hinge ofsaid handle. When the handle 22 is broughtdown. so that as the die ispressed upon the bed plate -23, the cam -18 is forced between the plates2% and 25 and forces the plate 24, carrying the end sections of the dieoutwardly and thus expands the dieso that it occupies the space desiredupon the lank resting upon the bed plate 23. 'hen the die head 13 israised by the handle 2:? the link .20 draws the cam 21 out from be:tween the plates 24 and 25 and the spring 2'? draws the plat? 2-1 backagainst the plate 25 and draws the die section out from the fold of theblank which has been pressed over the edge of the die so that the blankmay be removed by the operator without interfering with the fold of theblank. Thc die blade is made of very thin spring steel 5 and may bereinforced for part of its width where it is joined to the plates. Q-l.2-3 and 26 by reinforcing plates 56 and 57. see Fig. 13. which arefixedlv attached to the chest.

comes the cranking due to the contractio being slightly shorter than thehandle 22.

die blades are-so attached that they may be readily removedand otherssubstituted of the various size and shapes to form the style of collaror culi' desired. The plate 26 is adjustable on the plate '28 as tolength only.

The top suriace of the vertically movable steam chest "23 being the bedplate upon which the pressing is done and being verticallvniovable.steam is supplied through any suitable means as by the universal balljoints 39. and a similar joint is used to allow the condensed steam todrip from the steam This IHHYQI'SZtlbflll oint also overand expansion ofthe steam pipes. g0

Figs. 28 and 29 show a spider ($0. the four corners 61, (3'2. 63 and (34of which are rigidly attached to substantial parts of the machine, whilein the center are bearings (37 to guide the rod 19 attached to thetieadle 17 for 5 raising the bed-plate 23, said bearings make a solidand substantial support so as to move the bed-plate :23 evenly andpositively.

51, (3.). G6 arebraces or'fingers which are attached to substantialparts of the ma o chine and rest over the folder-plates when thefolder-plates are folding the goods over 'the die. so that when thepressure [5 exerted upon the foot pedal 17 and the bed plate 23 pressedupward the braces will hold the folder plates down and the goods will bethoroughly pressed with as much force as is desired between thefolder-plates and the bed-plate of the machine over the edges of thedie. 7. r Folder plates are here shown to be heated 9 by-stationaryboxc; located under them containing a heating medium, but the folderplates may also be made hollow and heated by electricity, for which Ihave fileda divi- I i I siomtl: plication. Constructed-in this man-. nerthe older pl ates are always hot when they are moved inward to fold theedges of the goods over the die and make a smooth uniform fold overthethin die. The dieisso thin that it is heated by the bed-plate and thefolder-plates. The die remains within'the fold until after thefolder-plates are removed and then as the die head is raised the diecontracts; autonmtically and withdraws from the folds of the goods andleaves the folds smooth and uniform in the best possible condition forstitching. i

To operate the nuichiue, the handle 2" with the die is raised as high asnecessary to leave the bed plate free for the placing of a blankthereon. This movement of the handle raises the connecting rod 33 andthrough the lever 31 and other connecting parts the rod 19 is raised tocarry the bed plate against the under surface of the folder plates inorder to keep them hot. these folder platesz, it is understood. lXfilHEin their replates 24. 25 and 26 and to which the die tracted positions.so that a blank w ll rest 65 blade sections are removably attached.

The die is now 139 lowered ontothe blank, this movement also loweringthe bed-plate'sli'ghtly, the differ.- ences in movement of the two beingcompensated for by lost motion between the connectmg rod 33 and thelever 31. Pressure is now applied to the treadle 17 toraise the bedplate 23 againstthe folder plates, at the same time rocking thecross-arm 31, the pin 14 movingupwardly in: the slot at the lower,
